RADIATOR HEATER.

Application filed September 20, 1920. Serial No. 411,511.

To all whom it may concern: v

Be it known that I, ARTHUR IV. HARPER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to Radiator Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention has for its object to proride means for preventing the freezing of automobile radiators in cold weather. It provides a means for reducing the amount of radiation of the heat. In moderately cold weather a reduction of the radiation of the heat will prevent the freezing of the radiator to which constructions containing my invention may be attached. I also have provided in connection with my invention a means for heating the radiator when the rate of radiation is large, which occurs when the weather becomes severely cold.

The invention may be contained in structures of diflerent forms. To illustrate a practical application of a construction con taining my invention I have selected one of such constructions and shall describe it hereinafter. The structure selected is illustrated in the accompanying drawing.

Figure 1 of the drawings is a front view of a radiator cover containing my invention, Fig. 2 is a sectional view of the cover. Fig. 3 is a side View of a means for securing adjustable blades or" the cover. Fig. 4 is a front view of the means illustrated in Fig. Figs. 5 and 6 show the position of the blades when opened and when closed.

In Figure 1, 1. is a shell that constitutes a cover for closing or covering the front side of the radiator 2. It has an extending flange 3 that surrounds the neck 4 of the in let ot the radiator, and it also extends over the sides of the radiator 2 and so as to tightly fit the top and sides of the radiator. The cover 1 is provided with a frame 6 which is pivoted along its top edge to the upper part of the cover 1. It is secured in closed position by means of the latches 7 located at the lower edge of the frame 6.

The frame 6 is provided with a plurality of blades 8 which are pivoted on rods 9 that pass along the horizontal center lines or" the blades 8, The inner edges of the blades are connected by horizontal rods 10 through the vertical rod 11. may thus be opened and closed by movement of the rod 11.

The lower blade 8 is provided with a spring latch 12 having the bolt 13, and the frame 6 is provided with a plate 14 having openings 15 arranged in the form of an arc centering in the rod 9 on which the lowermost blade 8 is pivoted. The open- The blades 8 ings 15 are so arranged that the bolt 13 may be inserted in any one of the openings 15. The bolt 13 will thus secure the blades 8 in any one of the positions where it may be inserted in one of the openings 15. By this arrangement the blades may be adjusted relative to the frame 6 so as to vary the angle of the blades 8 and thus vary the opening between the blades.

The blades 8 are provided with curved edge portions 16 that extend downward and under the rods 10. The curved edge portion of each blade thus extends beneath the rod 10 located in the upper edge of the next lower blade. This provides an elastic sealing means between the blades when they are in closed position as they make elastic contact against the succeeding blades and prevent water although it may be dashed against the cover, from entering the cover 1.

In order to heat the radiator during cold weather, a heating means may be located within the cover 1. Any form of heating means may be used. I have shown in the particular construction selected, an oil heater 18 having a gauze shell 19 to prevent flickeringand also to prevent explosion in case any gas vapors should enter the cover 1.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

In a radiator heat protector, a cover for enclosing the radiator and covering the front end thereof, a frame connected to the cover and having a plurality of blades pivoted to the frame, a rod connecting the blades and a latch bolt and perforated bracket for securing the blades at different angles With respect to the frame, the blades each having a downwardly curved outer edge adapted to make contact withportions of the blades along the upper edge of the next adjacent blade and below the axes of m rotation of the blades when the blades are in closed position, and a" heater located within the cover for heating the interior of the cover. 7

In testimony whereof 1 have hereunto signed my name to this specification.

ARTHUR W. HARPER.
